Bodyweight progression

Toes-to-Bar

Trains core first, with real work landing on forearms, lats.

Muscle contribution per set

Core1
Forearms.30
Lats.15

These are the weights Forge's volume audit actually computes with — deliberately conservative, so compounds don't masquerade as full coverage. A 0.5 means a set counts as half a set for that muscle: meaningful help, not a replacement for direct work.

Tempo

2down
0pause
2up
0squeeze

Dynamic hanging core movement with tempo; builds lower ab and hip flexor strength plus grip.

Controlled swing or strict; touch bar with toes, lower with control.

Derived from tempo research on this movement class — Schoenfeld BJ, Ogborn DI, Krieger JW.

How Forge progresses it

Progresses by reps, not weight — you earn harder sets, longer holds, or extra reps rather than plates.

Swap it for

Same movement pattern, same progression continuity — these are the alternatives the app offers mid-session when a rack is taken or equipment isn't there.

Train with intention. Open Forge — it prescribes the weight, watches the reps, and does this arithmetic for every set you log.
